Chart 11 shows the contribution to uncertainty each sector makes by way of a horizontal bar chart. Projections and estimates of carbon dioxide removals by forest sinks are the largest source of uncertainty with an absolute uncertainty range of 54.1 million tonnes carbon dioxide equivalent. Absolute uncertainty by sector was projected as follows (million tonnes carbon dioxide equivalent):
| Sector | Million tonnes carbon dioxide equivalent |
|---|---|
| Removals via forest sinks | 54.1 |
| Agriculture | 41.9 |
| Deforestation | 32.2 |
| Energy (excluding transport) | 18.4 |
| Transport | 12.6 |
| Industrial processes | 0.8 |
| Waste | 0.3 |
| Solvents and other product use | <0.1 |
